Re: Commands to create matrix in TI-89



>Does TI-89 have commands to create and edit a matrix from programs?


Yes.  newMat(R,C) creates a zero-filled matrix of R rows and C columns,
randMat(R,C) creates a matrix of random integers between -9 and 9.  To edit
a matrix from a program, you can use subMat to extract a sub-matrix and you
can alter each element of the matrix directly by assigning new values.
